and Rely Less on the Grid
Professionally designed solar-panel and battery-storage systems for homeowners across Scotland and Northern England. Generate clean electricity, store surplus energy and use more of your own power after sunset.
Certified Installation. Trusted Support.SG Retrofit provides professionally designed and installed renewable-energy solutions, supported by recognised industry standards and customer protection.
Generate clean electricity at home with a system designed around your roof, energy use and future requirements.
Generate energy during daylight hours, store unused electricity and use it when your household needs it.
Already have solar panels? Add compatible battery storage to retain more of the electricity your system generates.
Generate your own electricity and reduce what you buy from your energy supplier. Many households see meaningful reductions in their monthly bills.
With battery storage, the solar energy you generate during the day doesn’t go to waste. Use it in the evening when electricity demand and costs are typically higher.
Reduce your exposure to future energy price increases by generating and storing more of your own power.
Depend less on the grid and gain more control over your household energy supply.
Modern solar and battery systems are designed for quiet, reliable operation with minimal upkeep.
Battery storage transforms how you use solar energy. Instead of exporting surplus electricity back to the grid during the day, you store it for use in the evening, at night, or whenever your home needs it most.
We install batteries as part of new solar systems and retrofit them to many existing installations. Our team will assess your current setup and recommend compatible storage options.
